Recently bought a Total Nv. I have drilling number 3 on the ball that has a 1-2 out pin. First two weeks with factory 4000 finish on ball on medium oil, reacted really late. Took finish down to 1000 polished on same lane condition and got pretty much same reaction, a tad more break. Question is if i would have bought a ball that had a 4 to 5 out pin,with drilling 3 would it react better and hook more? I tell you what's killing me is people in my league with half the revs as me getting the ball to hook more. Thanks Ben.

The TNV goes long, longer than Angular One. A pin out might hook a little more, but your best bet is to scuff the surface. I'd try 2000 abralon, no polish, and adjust from there.

THANSK,BUT OTHER GUYS IN MY LEAGUE HAVE THERE TOTAL NV OUT HOOKING MINE WITH LESS REVS AND SIMILAR DRILLINGS.ALL I COULD THINK OF THAT WAS CAUSING THIS TO HAPPEN WAS THEY HAVE THERE PINS OUT 4 TO 5 WHERE MINE IS 1 TO 2 . WHATS DOES HAVING A PIN OUT 5 GIVE YOU COMPARED TO A PIN OT ONLY 2 ?

It gives you a slightly more unstable core. Think about it this way, on a ball with a symmetric core, if the weight block is perfectly in the center of the ball, the cg and pin would be in the same place, with the top of the weight block being the heavy spot. Pin out balls result when the weight block is shifted slightly to one side, putting the heavy spot on the ball away from the pin. It makes for a slightly more unstable core movement around the axis point. When 2 piece balls first came out (hammer, etc) pin out balls were thought of as mistakes or almost seconds.
Their balls also might have a little more thumbweight, because of the cg positioned closer to the thumb, causing an earlier read, but this would have a VERY minor effect compared to other factors.
Hope this helps

Revs do not always equate to hook potential. Side roll, axis tilt, and axis rotation all play a big part in hooking the ball. I throw with nearly as many revs as my son. He normally throws the 5th arrow or so and bounces it off the 2 board at 20 mph. I, on the other hand, throw about 16 mph, my taget is about 13 board and my breakpoint is usually the 5 board. Sometimes I dont come up quite soon enough. Watching us bowl together is a mystery for those who cant see axis tilt and rotation. They have no idea why he outhooks me by 200%. Just keep in mind that not everything is as it seems.

hey,
to clarify what Cobalt Bomb said, generally speaking the longer the pin the more length and "pop" you get, I prefer longer pins unless I'am bowling on longer or heavier patterns due to my high rev rate, but as an observation people with lower revs seem to have more of a problem with them not reving fast enough. Just my opinion, hope this helps.
